Can cochlear implantation restore spatial hearing in adults with single-sided deafness?

Pádraig Kitterick, PhD

Acquired unilateral severe-profound sensorineural hearing loss, or single-sided deafness, can have a severe detrimental impact on an individual’s quality of life. The total or near-total loss of binaural cues has a hugely disruptive effect on listening in and navigating everyday environments. Cochlear implantation holds great promise as an intervention that could address the difficulties that these individuals face, by restoring bilateral access to sound. Previous studies have demonstrated that cochlear implantation reduces localisation error and improves speech perception in noise in these adults. I will present data from a prospective multi-centre study of cochlear implantation in adults with single-sided deafness whose aim was to better understand the nature of improvements to spatial hearing and hearing-related quality of life. The spatial listening abilities and self-reported listening difficulties of adults with acquired unilateral severe-profound sensorineural hearing loss were assessed at baseline and after being implanted unilaterally. Sound localisation was assessed in an anechoic chamber before and 9 months after implantation using a 48 loudspeaker array that was capable of recreating the patterns of reverberation that arise in a variety of listening environments. Detailed information on their listening performance, device programming, device usage, and the extent to which they listened to training materials through the implant alone were recorded. I will present analyses of their localisation performance and identify what factors influenced whether a patient receives spatial benefit, and discuss the implications for candidature and rehabilitation. I will also discuss the extent to which the benefits to spatial hearing observed in the laboratory could be generalised to benefits in everyday life.

Motor Speech Disorders and Dysphagia in Progressive Supranuclear Palsy

Heather M. Clark, PhD

Consultant and Chair
Division of Speech Pathology, Department of Neurology
Mayo Clinic Rochester

Progressive Supranuclear Palsy (PSP) is the most common of the Parkinson Plus syndromes. Bulbar dysfunction occurs early in the disease and may even be the presenting symptom of the neurodegenerative process. This talk will review motor speech and swallowing findings from a large cohort of participants with common and uncommon variants of PSP, exploring pathophysiologic mechanisms contributing to patterns of deficits across variants.

Seminars in Hearing and Communications Sciences (SHACS)

 

Seminars in Hearing and Communications Sciences is a lecture series designed to engage the multi-disciplinary hearing and balance, speech and language science community at the UW. A joint venture between the Department of Speech and Hearing and the Virginia Merrill Bloedel Hearing Research Center, SHACS provides rich continuing education experiences for students at all levels as well as faculty during the fall, winter, and spring quarters. Lectures are generally held on Friday afternoons at least twice a month, though there are periods with more frequent lectures, some of which fall outside of the regularly scheduled time. Speakers may be recruited from universities across the country, internationally, or from our own UW campus.

When we host a lecturer from outside the university, we often schedule additional events as opportunities to professionally connect with the speaker. These may include one-on-one meetings, catered lunches with graduate students and postdocs on campus, faculty networking dinners, and post-lecture receptions.

The committee for planning the SHACS lecture series is usually formed in early autumn, with the first lecture in October once the new academic year starts – look for more info here and on the email list in September.

This list provides info on SHACS lectures in the near future with bios of the speakers and talk abstracts; non-SHACS events on topics of related interest are sometimes promoted on this list as well. This is an announcement-only email list rather than a discussion list, so postings are only made by the moderators and will be sent a few times a week at most.
